I have just jumped on board the HT bandwagon. I have new Marantz SR-7000 and I don't see any way to hook up my cable/TV to the receiver! My Sony 27" is a little old and does NOT have S-video or composite video out (it has cable in, composite video/audio in, and composite audio out). Of course, the Marantz manual isn't much help either! Any ideas (other than buying a new TV)?
